[0002] Printed circuit board storage devices are equipment specifically designed for the safe and orderly storage of printed circuit boards, aiming to protect PCBs from physical damage.

[0003] Currently, most existing storage devices are fixed trays or simple pull-out structures, with printed circuit boards placed directly flat in the drawer. When retrieving them, it is often difficult to grasp them because the boards are tightly attached to the tray and there are no leverage points on the edges. This is especially true for thinner circuit boards, which require the assistance of tools, making the operation cumbersome. In view of this, we propose a storage device for printed circuit boards.

[0017] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-9 This utility model proposes a storage device for printed circuit boards, including a cabinet 1 and a drawer 2. The inner wall of the cabinet 1 is connected to a support rod 11, and the end of the support rod 11 is provided with a slot 12. A pin 14 is inserted into the slot 12, and a limit block 13 is connected to the outer wall of the pin 14. By designing the limit block 13 to be inserted, the limit block 13 can be removed from the support rod 11, and the entire drawer 2 can be removed from the cabinet 1. The drawer 2 is provided with a lifting mechanism.

[0020] In this embodiment of the utility model, to facilitate the removal of the printed circuit board, the lifting mechanism specifically includes a housing 23, a sliding groove 231, a moving rod 24 inside the housing 23, a shaft 242 connected to the outer wall of the moving rod 24, the shaft 242 being slidably connected to the sliding groove 231, the moving rod 24 having a hollow design, a roller 241 rotatably connected to the inner wall of the moving rod 24, and a return spring 244 connected to the outer wall of the moving rod 24, with the end of the return spring 244 away from the moving rod 24 being connected to the inner wall of the housing 23. The moving rod 24 is fixedly connected to the outer wall of the moving rod 24. The long rod 243 passes through the housing 23 and the drawer 2 and is slidably connected to the housing 23 and the drawer 2. The end of the long rod 243 is connected to the pull rod 245. The bottom of the tray 21 is hinged to the hinge rod 25. The end of the hinge rod 25 away from the tray 21 is passed through the shaft 242 and is rotatably connected to the shaft 242. There are two sets of support rods 22, which are fixed on both sides of the drawer 2 respectively. The support rods 22 have through grooves 221, which are slidably connected to the pull rod 245. The tray 21 has a notch 211, and a limit rod 212 is connected to the outer wall of the tray 21. A protrusion 213 is connected to the outer wall of the limit rod 212. A limit groove 200 is opened on the inner wall of the drawer 2. The limit groove 200 is slidably connected to the protrusion 213 to limit the tray 21 and improve the stability of the tray 21 lifting. In this invention, when it is necessary to remove the printed circuit board from drawer 2, drawer 2 is pulled outwards, and drawer 2 moves outwards along the track of cabinet 1 under the pulling force. It should be noted that the length of the support rod 22 at the bottom of drawer 2 is greater than the length of drawer 2 itself.

[0021] After drawer 2 is completely detached from cabinet 1, a pulling force is applied outward. At this time, the pull rod 245 at the bottom of drawer 2 will contact the limiting block 13 on cabinet 1. The limiting block 13 will apply reverse resistance to the pull rod 245, forcing the pull rod 245 to move inward towards the drawer 2. The long rod 243 and the moving rod 24, which are fixedly connected to the pull rod 245, will move synchronously. At the same time, the return spring 244 connected between the pull rod 245 and the inner wall of drawer 2 will be stretched and enter an elastic deformation state.

[0022] When the lever 24 moves, its end shaft 242 applies a pushing force to the hinge lever 25, causing the hinge lever 25 to rotate downwards around the hinge point with the tray 21. During the rotation of the hinge lever 25, it lifts the tray 21, causing the tray 21 to move smoothly upwards along the limiting groove 200 on the inner wall of the drawer 2. Figure 2 As shown, the printed circuit board placed on the tray 21 will eventually be pushed out of the drawer 2 plane, making it easier for the operator to grab. In addition, the edge of the tray 21 has a notch 211, which can reserve space for fingers to insert, so as to avoid the printed circuit board being too tight to be grabbed due to the tray 21, and further improve the convenience of taking out the printed circuit board.

[0023] When drawer 2 is pushed inward, drawer 2 moves inward along the track of cabinet 1. At this time, the reverse resistance of the limiting block 13 on the pull rod 245 gradually decreases until it disappears completely. After the force of the limiting block 13 is lost, the moving rod 24 will be driven by the elastic force of the return spring 244 to drive the long rod 243 and the pull rod 245 to return to the initial position synchronously.

[0024] During this reset process, the shaft 242 at the end of the moving rod 24 will again apply a pulling force to the hinge rod 25, causing the hinge rod 25 to rotate upward around the hinge point with the tray 21. As the hinge rod 25 rotates, its supporting force on the tray 21 gradually transforms into a pulling force, causing the tray 21 to slowly move downward along the limiting groove 200 on the inner wall of the drawer 2, eventually causing the tray 21 to fall back and be stored inside the drawer 2, restoring its initial placement state so that the drawer 2 can be fully pushed into the cabinet 1.

[0025] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
